TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented June 3, 1913.

Application filed April 6, 1912.. Serial No. 688,849.

To all whom it ma concern: 7

Be it known that I, JOHN C. l\.'lcL.muur.n-z, a citizen of the United States, residing in Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Type- Writing Machines, of which the following is a specification.

This invention relates to combined paper depth gage and paper support, and is an improvement on my application No. 688,331, filed April 3, 1912.

I have set forth in my application No. 688,331 above mentioned, the advantages of a paper depth gage of the general character of that used in this invention, whereby the typist can tell at a glance when a given number of lines have been written on the work sheet, or in other words, when the bottom edge of the work sheet has been approached by the typewritten matter up to a predetermined desired limit.

The use of a paper support, projecting from the platen frame for holding the paper in a raised position out of contact with the typewriting machine proper as it comes from the platen, is well-known in the art, in connection with such machines as the Underwood.

It is the purpose of this invention then, to combine a paper depth gage with a paper support, whereby the functions of the two will be merged in one device, giving a simplicity of structure and a cheapness of manufacture. In the carrying out of this purpose, the standard of the gage is formed integral with the paper support, that is to say, they are bent up from the same strip of wire. The combined paper support and gage is hinged to the platen frame, so that it can be swung from an operative position projecting outwardly to an inoperative position lying on top of the typewriter.

Other features'and advantages will here inafter appear.

In the accompanying drawings, Figure 1 is a vertical section through the upper part of a typewriter, showing the combined paper support and paper depth gage 1n use, and with the paper or work sheet 1n a position corresponding to the writing of the final line, which it is desired to write, on the sheet. Fig. 2 is a fragmentary perspective view, showing the combined gage and paper support in its erect operative posltion. Flg.

Z} is a fragmentary perspective view, showing the relation of the stop to the standard.

Referring more particularly to the separate parts of this invention as embodied in the form shown'in the drawings, 1 indicates the typewriter or typewriting mechanism, only a part of which is shown, and which may include the usual carriage'having a platen frame 2 on which'is supported a platen The platen 3 supports and feeds a work sheet indicated at 4, so that the latter will be fed by a printing point indicated at 5, where it will be struck by the type on type bars 6 actuated by suitable key mechanlsm, not shown.

If it is desired to ascertain when the end of the sheet 3 is approached, it is necessarv to have some outside means of indicating this condition of allairs, because of the fact that the bottom edge of the work sheet- 4 is concealed at this time between the platen 3 and a paper shelf 7 which guides the paper or work sheet to the platen. It is often also desirable to support the work sheets, especially where there are several carbons being made, out of contact with the body portion of the typewriter as it comes up from the platen. Inthis invention, the means for supporting the paper, and the means for gaging the extent which the paper has passed through the typewriter are combined in one, so as to form a simple and inexpensive structure. To effect this result, there may be provided on the platen frame 1, brackets 8, which are perforated to form bearings for the ends of a wire 9, which extend through these openings, and may be bent up as at 10 to secure them in position.

The wire 9 is bent intermediate its ends to form a series of minor loops 11 and one major loop 12, located intermediate a plurality of minor loops. It will be noted in passlng, that the reachesor sides of the minor loops extend-at angles to each other, so as to form a spread supporting surface well adapted to support the work sheet or paper coming from the platen. The reaches of the major loop 12, however, are brought parallel with each other, so as to form an elongated standard on which may be adjustably mounted a stop 13. In order that all of the loops which together comprise the paper support and the standard of the paper gage may be united together to form a substantially rigid and firm structure, there is i provided a brace 14: which overlaps all of these loops, and atits ends indicated at 15,

:-i's"cu rled*about the wire 9. The points-of crossing or contacting of the intermediate reaches of the several loops with the brace It may be joined together in any suitable manner, as by brazing or soldering.

It will be seen that in view "of tl1e-"fa'ct that the wire 9, whiclr embodies the parts of the paper gage and paper support, is pivotally mounted on the lug 8, that it can be swung from the erect position shown-1n Figs. 1 and 2, to a position lying down .on topof the platen frame 2.

To prevent a rearward swinging move ment beyond the inclination shown in Fig. 1, there are provided on the brackets 8 lugs 16, -which project into the path of movement of the wire 9, and form a support therefor.

' It will be seen by reference to Figs. 2 and 3, that the standard formed from the elongated loop 12 is provided with a series of notches 17, which may be located at intervals corresponding to the spaces between lines written by the typewriting mechanism on the work sheet 4.. These notches enable the stop 13' to be locked in any adjusted position on the standard 12 by a latch 18,

' which is pivotally mounted on the stop.

each other, whereby the standard 12 can ex tend through them. The strip of metal is also bent so that the arms 21 and 22 extend parallel to each other, and form standards for the pivotal mount of the latch 18. This latch may be provided with an integral spring tongue 23 struck out of the body of the latch, and normally engaging the stop 7 13,- so asto tend to force the gripping edge of the latclrlfi in engagement with the standard 12.

That portion of the stop 13 which contains the opening 20, is extended forwardly a considerable distance beyond the standard 12, so as to forma projection or extension 24,

. forming at its junction with thestandard 12 a stopping corner in which thetop edge of the-work sheet 4 will readily engage and be caught against further movement.

In order to set the gage portion-of this device to correspond to any desired number of lines to bewritten on a particular work sheet,

- orin other words, to correspond to a certain limit'of approach of the typewritten-matter to-the bottoni edge of the work sheet, a trial sheet of the size desired is run over the platen-unt1l a previously placed mark corresponding with thelast desired line of typewriting-comes into register with the 13 can then lie-adjusted, aft-er first releasin'g-the latch 18, pntilthe junction'pf the extension "24 and the standard '12 abuts against the top edge of the Work sheet 4.

Any subsequent work sheet of the same size will then be caught under the same cond ition, and'will indicate that the desired hmit of 'typewriting has been reached for that particular work sheet.

If it is not desired to use-the'gage feature of this invention, the stop 13 can be run up or down on the standard 12 out "of the way and then the connected loops Wlll form an "etiicient paper support for holding the paper,

as it comes up over from the platen, out of contact with the typewriter proper. If-it is desired to close the machine for thenight, the combined support and gage can be swung as one piece, to a position lying on.

top of the platenfra-me, where it willbe out of the way.

Variations may be resortedto within the scope of the invention, and portions Of-tilleimprovements may be used without. others;v
